Ultrasonically bonded fabric and method of making same

Abstract

An ultrasonically bonded fabric comprising a non-woven coverstock treated with an organosilicone material, e.g., an organosilicone fluid, prior to being ultrasonically bonded to another material. The ultrasonically bonded fabric as made by treating a non-woven coverstock with the organosilicone material and ultrasonically bonding the treated non-woven coverstock to the other material.

What is claimed is: 
     
       1. An ultrasonically bonded fabric comprising a non-woven coverstock that is ultrasonically bonded to an anti-wetness material wherein an absorbent material is positioned between the coverstock and the anti-wetness material and wherein the coverstock is treated with an organosilicone material prior to being ultrasonically bonded to the anti-wetness material to prevent failure of the fabric. 
     
     
       2. A disposable device for absorbing and containing liquids comprising a liquid permeable coverstock bonded to a liquid impermeable back sheet to enclose an absorbent element therebetween, said liquid permeable coverstock having dispersed thereon an organosilicone surfactant. 
     
     
       3. The disposable device as claimed in claim 2 wherein the organosilicone is dispersed in an amount of 0.001 to 0.004 g/m 2  of said liquid permeable coverstock. 
     
     
       4. The disposable device as claimed in claim 2, wherein said organosilicone material is an organomodified polydimethylsiloxane.
